Magistrsko delo obravnava varnost oblačnih sistemov za shranjevanje podatkov. Glavni namen magistrskega dela je predstaviti varnostne mehanizme, ki zagotavljajo varnost podatkov v tovrstnih sistemih. Predstavljene so varnostne grožnje, ki lahko ogrozijo podatke ter predlogi, kako se pred njimi zavarujemo. Uvodno poglavje vpelje bralca v tematiko magistrske naloge. V drugem poglavju je obrazložen princip računalništva v oblaku. Predstavljeni so izvedbeni in storitveni modeli, ki jih srečamo pri uporabi računalništva v oblaku. V omenjenem poglavju zasledimo tudi prednosti in slabosti računalništva v oblaku. Tretje poglavje opisuje varnostne postopke ob dostopu do storitev ter varnost pri hrambi podatkov. V nadaljevanju poglavja sledi opis deljenja datotek ter z njim povezano dodeljevanje pravic uporabnikom in varstvo osebnih podatkov. Narejena je tudi primerjava med brezplačnimi in plačljivimi storitvami ter predstavljeno zakaj in kako lahko najbolje sami zavarujemo podatke. Četrto poglavje predstavlja varnostne grožnje računalništva v oblaku katere prepoznava tudi organizacija Cloud Security Alliance. Opisan je vpliv posamezne grožnje ter način, kako njen vpliv zmanjšati ter podana primera ugrabitve računa preko beleženja tipk in napad grobe sile na geslo. V petem poglavje je predstavljena strategija Evropske komisije na področju računalništva v oblaku. Poleg tega je podana raziskava o uporabi tovrstnih storitev, o priljubljenosti sistemov za shranjevanje podatkov glede na starostne skupine, namenu uporabe storitve ter razlogih za uporabo oziroma neuporabo oblačnih sistemov za shranjevanje podatkov. V zadnjem poglavju so podane sklepne ugotovitve. The master's thesis deals with the safety of cloud data storage systems. The main purpose of the master's thesis is to present the security mechanisms that ensure the security of data in such systems. It also presents security threats that can endanger information and suggestions on how to protect ourselves from them. In the first chapter the reader is introduced to the topic of a thesis. The second chapter explains the principle of cloud computing. Operational and service models that we encounter in the use of cloud computing are featured. Within this chapter the pros and cons of cloud computing are traced. The third chapter describes the safety procedures on access to services and the safety of data storage. A description of sharing of files and the allocation of rights associated with that to users and protection of personal data follows. And a comparison between the free and paid services is made. Also how to best protect information yourself is presented in this chapter. The fourth chapter presents security risks of cloud computing which recognizes the Cloud Security Alliance organization. The impact of each threat and how to minimize the impact of threats is described and given an example of abduction account through keylogging and brute-force attack on password. In the fifth chapter the strategy of the European Commission in the field of cloud computing and research on the use of such services are presented. The survey provides data on which age group data storage systems are most popular and the purpose of use of the service and reasons for using or not using cloud data storage systems are listed. Conclusions are presented in the last chapter.
